Resistant to the pressure and freeze
O- ring made of silicone rubber is resistant to the pressure and is suitable for storage in liquid nitrogen (vapor phase) or the deep freezer.

Precautions: Handling Screwcap Tubes under the Liquid Nitrogen

In terms of safety, store the screwcap tubes in the vapor phase.
To avoid any risks such as the tube rupture and the sample spatter, do NOT handle the screwcap tube under the liquid phase.
Fill up the test sample into the body of the screwcap tube up to the degree of 90% of the maximum content.
Wear a face shield, protective clothes, and gloves when handling liquid nitrogen for defrosting.

Shading screwcap tube
This light-shielding screw-cap tube is capable of thoroughly shielding light of short to long wavelengths and is best suited for use in experiments on samples susceptible to light, such as bilirubin, as well as their storage.
